The xps_ll_temac contains its own PLB interface. Consequently, the logic connecting
the "PLB Interface" of the Ethernet AVB Endpoint core to the Host I/F (as seen in
Figure 5-1) is not present in this case.
The "Legacy Traffic Interface"
directly to the xps_ll_temac; this allows the xps_ll_temac core to source and sink
legacy frame data, such as TCP/IP protocol traffic. The full duplex
Interface" remains for connection to custom logic.
The "MAC Header Filters", as seen in
xps_ll_temac instead contains its own Address Filter logic.
